Johnson & Johnson Announces Its First Phase 3 COVID-19 Vaccine Trial ENSEMBLE is Fully Enrolled

Dec 17, 2020
United States

The large-scale, pivotal, multi-country Phase 3 trial (ENSEMBLE) of the investigational Janssen COVID-19 single-dose vaccine candidate is now fully enrolled with approximately 45,000 participants. Given the high incidence of COVID-19 among the general population in the countries where the trial is being conducted, this number of participants will be sufficient to generate the data needed to determine the efficacy and safety of the Company’s investigational COVID-19 vaccine candidate. Johnson & Johnson expresses its thanks to all participants, trial sites and health care professionals involved in the ENSEMBLE study.

Interim data from the ENSEMBLE trial is currently anticipated to be available by the end of January 2021. However, as this trial is dependent on disease events, the timing is approximate. If the data indicate the vaccine is safe and effective, the Company expects to submit an Emergency Use Authorization application to the U.S. Food and Drug Administration (FDA) in February. Other health regulatory applications around the world will be made in parallel.

Johnson & Johnson continues to develop and test its COVID-19 vaccine candidate in accordance with high ethical standards and sound scientific principles. The Company is committed to transparency and sharing information relating to the Phase 3 ENSEMBLE study.

ENSEMBLE was initiated in collaboration with the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services (HHS) under Other Transaction Agreement HHSO100201700018C, and the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH) at HHS.

A separate Phase 3 clinical trial of the investigational Janssen COVID-19 vaccine candidate to explore a two-dose regimen of Janssen’s vaccine candidate (ENSEMBLE 2) is ongoing.
